It is possible to write five as a sum in exactly six different ways:
$$\begin{align} &4 + 1\\ &3 + 2\\ &3 + 1 + 1\\ &2 + 2 + 1\\ &2 + 1 + 1 + 1\\ &1 + 1 + 1 + 1 + 1 \end{align}$$How many different ways can $2^N$ be written as a sum of at least two positive integers? Give your answer modulo $1000000007$.
